And for comparison with VB Pro using the €10 deal which gives you €5 credit, and therefore costs €5 for a year of calls:
1 call a week: 52 calls for €5 plus 3.9c/call = 13.5 cents per call
2 calls a week: 104 calls for €5 plus 3.9c/call = 8.7 cents per call
10 calls a week: 520 calls for €5 plus 3.9c/call = 4.9 cents per call
Best price trends towards 3.9 cents per call
In other words, make more than 1 call a week and you're better off on VB Pro. Make 1 call or less each week, and you're probably better off with Nadiz. And if you make even fewer calls to paid destinations, like I do, then you're better off just paying for each call
